Quick Answer: The best metal detector shaft in 2026 is the Garrett Carbon Fiber 2-Piece Shaft (about $89.00) for AT MAX, AT PRO, ACE 400 and ACE 300 owners — it drops the stock aluminum shaft’s weight without changing anything else about the detector. XP Deus II and ORX owners get more from the XP S-Telescopic Stem with Armrest (about $159.00), a full ergonomic redesign rather than a material swap, and anyone on a tight budget needing a quick fix should look at Garrett’s Middle Shaft with Camlocks (about $14.99), a direct OEM replacement for a cracked stock rod.
A shaft is the one part of a detector that takes the most physical abuse — camlocks strip, middle rods crack after being dropped on rocks, and stock aluminum starts to feel heavy by hour three of a beach hunt. None of that means the detector itself is done. Below are six real replacement and upgrade shafts across the four brands this site covers most, matched to what problem each one actually solves: a broken part, a weight upgrade, or a full ergonomic redesign.

1. Garrett Carbon Fiber 2-Piece Shaft — Best Overall
Garrett Carbon Fiber 2-Piece Shaft
- Fits the AT MAX, AT PRO, ACE 400 and ACE 300 — the four most-reviewed Garrett models.
- Drops in as a direct swap for the stock aluminum shaft, no coil or control-box changes needed.
- Carbon fiber sheds several ounces versus stock, felt most on long multi-hour sessions.

If you run a Garrett AT Pro or AT MAX, this is the shaft that solves the most common complaint about those machines: stock aluminum starts to feel heavy well before a full day of swinging is over. It’s a straight material swap — the camlock spacing, coil mount and control-box arm cup are unchanged — so there’s nothing else to relearn about the detector once it’s installed.
2. XP S-Telescopic Stem with Armrest — Best Ergonomic Upgrade
XP S-Telescopic Stem with Armrest
- Full S-shaped redesign that routes weight through a forearm cup instead of a wrist grip.
- Fits the Deus II and ORX, XP's wireless coil-to-headphone lineup.
- The priciest shaft here, but the only one that changes swing mechanics rather than just material.
A straight carbon-fiber swap saves weight, but it doesn’t change how that weight is carried. The S-Telescopic Stem does — its armrest cup shifts the load off the wrist and onto the forearm, which matters most on the kind of all-day sessions Deus II and ORX owners tend to run. It costs about $70 more than Garrett’s carbon-fiber swap above, and that premium buys a genuinely different way of holding the detector, not just a lighter version of the same one.
3. Minelab Carbon Fiber Lower Shaft — Best for Equinox
Minelab Carbon Fiber Lower Shaft
- Purpose-built for the Equinox 700 and 900 — Minelab's own camlock and cable-routing spec.
- Carbon fiber construction cuts weight versus the stock lower rod.
- A Minelab-specific fit means no guessing on cable-clip placement or coil-lug spacing.
Equinox owners running the 900 or 700 are usually chasing multi-frequency depth on long sessions, which is exactly when a lighter lower shaft pays off most. Because it’s cut to Minelab’s own spec rather than a generic fit, the cable clips and coil lug line up without any trimming or adapter needed — a real advantage over aftermarket universal shafts.
4. Nokta Carbon Fiber Longer Lower Shaft — Best Budget Upgrade
Nokta Carbon Fiber Longer Lower Shaft
- Fits the Simplex, Legend, Score and FindX lines — Nokta's widest current shaft compatibility.
- Under $40, the cheapest genuine carbon-fiber upgrade on this list.
- Slightly longer than stock, useful for taller detectorists who want less stoop.
Whether you’re running a Legend 2 or a Simplex Ultra, this is the cheapest way to get real carbon fiber under the coil instead of stock aluminum. It’s roughly $50 less than the Minelab Equinox shaft above, and the extra length is a genuine bonus rather than a compromise for anyone who’s been stooping to compensate for a stock shaft that runs short.
5. Minelab Carbon Fiber Lower Shaft Assembly — Best for Manticore
Minelab Carbon Fiber Lower Shaft Assembly
- Built specifically for the Manticore's newer camlock and cable-routing geometry.
- Full lower shaft assembly, not just a bare rod — cable clips and coil lug included.
- Matches the Equinox shaft's carbon-fiber weight savings on Minelab's current flagship.
The Manticore shipped after the Equinox 700/900, and its shaft geometry isn’t interchangeable with the older line — this assembly is cut to the Manticore’s specific camlock spacing rather than a shaft that happens to also fit. At $90 it costs about $25 more than the Equinox version, in line with Minelab pricing its newest flagship’s parts at a premium.
6. Garrett Middle Shaft with Camlocks — Best Cheap Fix
Garrett Middle Shaft with Camlocks
- Direct OEM replacement for the ACE and AT series' stock middle rod and camlocks.
- Fixes the single most common shaft failure — a stripped or cracked camlock — for under $15.
- Stock aluminum, so it won't save weight, only restore the original fit.
Not every shaft problem calls for an upgrade. If a camlock has stripped or a middle rod cracked from being dropped on rocks, this is the part that fixes exactly that failure on an ACE or AT-series Garrett for under $15 — the cheapest real repair on this list, and the right call when the rest of the shaft is still fine.
Shafts by the numbers
- A complete Garrett carbon-fiber S-shaft system with a one-piece upper and 20-inch lower rod runs about $149-$159 plus shipping, roughly $60-$70 more than the standard 2-piece carbon-fiber shaft featured above, reflecting the added cost of the S-shaped upper (seriousdetecting.com dealer listing, 2026).
- Minelab prices its Manticore lower shaft assembly at $90, about $25 above the equivalent Equinox 700/900 shaft at $65, since the Manticore uses newer camlock and cable-routing geometry that isn’t interchangeable with the older Equinox line (detectorwarehouse.com retailer listing, 2026).
- Nokta’s carbon-fiber lower shaft, at $38.19, is the cheapest genuine carbon-fiber upgrade across the four brands compared here — less than half the price of the Minelab Equinox equivalent — while still fitting four current Nokta model lines (Simplex, Legend, Score, FindX) rather than one (detectorwarehouse.com retailer listing, 2026).
How to choose a replacement or upgrade shaft
- Match the exact model, not just the brand. Shaft camlock spacing and cable routing differ between models within the same brand — a Minelab Equinox 900 shaft doesn’t fit a Manticore, and a Garrett ACE shaft doesn’t fit an AT Pro. Check the listing against your detector’s exact model number before ordering.
- Decide whether you’re fixing or upgrading. A cracked camlock or stripped thread calls for a cheap OEM replacement like Garrett’s $14.99 middle shaft. A stock shaft that’s just gotten uncomfortable after years of full-day hunts calls for a carbon-fiber or ergonomic upgrade instead.
- Carbon fiber saves weight, not depth. None of the upgrades here change what a detector can find underground — they change how comfortable it is to carry for hours. Don’t expect a shaft swap to fix a depth or sensitivity complaint.
- Budget for the full assembly if cable clips are involved. A bare rod is cheaper than a full shaft assembly, but if the listing doesn’t include cable clips and a coil lug that match your model, you may need to source those separately.
- Pair a new shaft with the rest of your kit. A lighter shaft is most noticeable alongside the rest of a field setup — see our guide to metal detector bags and cases for how to carry the finished rig.
The bottom line
For most Garrett owners, the Garrett Carbon Fiber 2-Piece Shaft at $89.00 is the easy call — it fits four of the brand’s most popular models and cuts weight without changing anything else. XP Deus II and ORX owners get more from the S-Telescopic Stem with Armrest at $159.00, since it changes swing ergonomics rather than just material, and Minelab owners should match their exact model — Equinox 700/900 at $65.00 or Manticore at $90.00 — since the two aren’t interchangeable. On a tight budget, Garrett’s $14.99 middle shaft fixes the single most common failure without paying for an upgrade you don’t need.
